HOT-WATER GENERATO R.

SPECIFICATION forming part of Letters Patent No. 536,197, dated March 26, 1 895.

Application filed March 13, 1894. Serial No- 503 ,445. (No model.) i

To all whom it mag concern." I

Be it known that I, JOHN ENGELHA'R'I, a citi zen of the United States, residing at Akron, in the county of Summit, State of Ohio, have invented a new and useful Hot-Water Generator for Heating Purposes, of which the following is a specification.

My invention has relation to hot water generators for heating purposes, and among the Objects in view is to provide a simple, inexpensive and efficient generator adapted to quickly and with economy heat water, and to provide for a continuous flow of hot water through the pipes, thereby producing almost instant heat as soon as a fire is applied A further object'is to dispense with the use of packing,- and a-still further object is to provide for an immense amount ofhcating surface arranged in a very compact and small space. v

The invention consists in the novel, construction, arrangement, and combination of parts, as hereinafter fully described, illustrated in the drawings, and pointed out in the claim.

In the d1awingsz-Figure 1 is a front view of my heater, Fig. 2, a horizontal sectional view on line JK of Fig. 4:; Fig. 3, a vertical sectional view on line N-O of Fig. 2; Fig. 4, a vertical sectional view on line LM of Fig. 2.

A indicates the base of the heater formed by horizontally-arranged flues or .tubes with which latter communicates the return pipe G.

B and 0 indicate vertically-arranged tubes which communicate at their lower ends with the base A, and at their upper ends with the horizontally-arranged dome D while 0 Bindicate tubes constructed in a zig-zag shape,

which communicate at one end with the verical tubes and at the opposite end with the dome D.

E indicates the fiow pipe which runs from the dome D.

P indicates a cross-wall upon which the grate R rests.

The heater is provided with a covering Q not burn out or clog'up from sediment as long ascare is taken in keeping the same filled with water (necessary wear of course excepted). It will also be found that by reason of the heat coming in direct contact with the tubing, "no soot will adhere to the same, thus obviatingall cleaning.

The many advantages of my improved heater will be readily seen and appreciated bythose conversant with this class of apparatus. I v

What I claim, and desire to ters Patent, is p In a hot water generator, the combination with an inclosing'casing, of a base A consisting of a number of horizontally arranged secure by Letflues or tubes the vertically arranged tubes B, O communicating at their lower ends with the tubes of the base, a horizontally arranged dome D, with which the upper ends of the tubes B, O communicate, vertically arranged 'tubes B Of, having a zig-zag shape, one end of said tubes B C communicating with the tubes B O at points intermediate the height of the latter, and the opposite end communicating with the dome D, a flow pipe E running from the dome, and areturn pipe G communicating with the tubes of the base, all as specified.
